Key Events

1945 CE: End of World War II → World War II (1939-1945 CE) - Post-war infrastructure expansion, highway expansion
1945 CE: Cold War begins → Cold War (1945-1991 CE) - Infrastructure investment, defense infrastructure
1990s CE: Globalization acceleration → Globalization Acceleration (1990s CE) - Infrastructure expansion, global networks
2008 CE: Global Financial Crisis → global financial crisis 2008ce - Infrastructure investment, stimulus

About this entry

A draft entry preserved from civilization.study. Evidence grade: strong. 2 of 3 listed sources are fully documented; the rest are names only. Method and sources

Methodology Notes

Estimation method:
- OECD Infrastructure Statistics (comprehensive coverage)
- World Bank Infrastructure Data
- National statistics (United States, Western Europe)
- Transportation department data
- Cross-validation using GDP and fiscal data
Data quality: Strong (comprehensive official statistics)
Uncertainty range: ±5-10% (official statistics, high quality)
Limitations:
- Regional variation within Western/Atlantic civilization
- Different infrastructure types (highways, local roads, etc.)
- Infrastructure quality variation
Cross-validation:
- GDP data (infrastructure enables economic growth)
- Fiscal data (infrastructure investment)
- Trade data (infrastructure enables trade)

Integration with Corpus

Links to claims: Western / Atlantic Civilization (supports GGS Style axis assessment)
Supports patterns:
- Guns–Germs–Style (GGS) Axes and Success/Failure Mechanisms (high infrastructure sophistication supports strong Style axis - state capacity, coordination capacity)
GGS implications:
- Style axis: High infrastructure sophistication supports strong Style axis assessment - high infrastructure requires and demonstrates state capacity (infrastructure investment, coordination, maintenance)
- Economic dynamism: Infrastructure growth indicates civilizational dynamism and economic capacity
- Comparative advantage: Largest global infrastructure network (1945-present CE) indicates strong civilizational capacity and coordination
Framework integration:
- CAD: Material and institutional domains, persistence/transformation mechanisms, Style framework
- Infrastructure: High infrastructure sophistication enables infrastructure analysis

Notes

Infrastructure types: Roads, railways, airports, ports, telecommunications, energy systems
Growth drivers: Economic growth, suburbanization, globalization, government investment, military needs
Period variations:
- 1945-1970 CE: Highway expansion, aviation expansion, suburban infrastructure
- 1970-present CE: Infrastructure maintenance, high-speed rail expansion, information infrastructure
Regional variation: United States (larger road network), Western Europe (higher rail density, high-speed rail)
Infrastructure sophistication: High infrastructure sophistication (88-94/100) reflects state capacity and coordination
Event-data integration: Infrastructure growth linked to post-war expansion (1945), globalization (1990s), financial crisis (2008)
Data needs: More detailed regional infrastructure estimates, infrastructure quality data, infrastructure investment data
